Application filed December 6, 1924. Serial No. 754,304.

To all whom it may concern:

Be it known that 1, JOHN H. DOOLEY, a citizen of the United States,residing at New Bedford, county of Bristol, and Commonwealth ofMassachusetts, have invented an Improvement in aste Collectors forCombing Machines, of which thefol'lowing description, in connection withthe accompanying drawings, is a specification, like characters on thedrawings representing like parts. i

This invention relates to combing machines and particularly to combingmachines which are provided with a waste collector of the general typeshown in United States patent to Both, No. 905,233, dated December 1,1908, or United States patent to Belger, No. 1,106,073, dated August 4t,191 i The waste collectors shown 'in these patents comprise a casingwhich incloses the combing member and the stripping member, an airexhausting mechanism for are ating an air current through the casingwhich removes the waste from the stripping member, a rotary perforatedscreen located within the casing adjacent the eXit end thereof andarranged so that the air current passes through the screen whereby thewaste is deposited onto the screen, and a station ary member within thescreen which shields a portion of the periphery thereof from the actionof the air-exhausting means with the result that the waste which hasbeen deposited onto that part of the perforated screen through which theair current is passing will be carried by the rotation of the screenaround to that portion thereof which is shielded from the air currentand is condensed into a fleece or sliver by passing between aQfrictionally driven pressure roll and the rotary perforated screenafter which the sliver is removed and drops into a can or other similarreceptacle suitably placed for this purpose.

In operation of waste collectors of this type it sometimes happens thatthe frictionally driven pressure roll fails to properly function due tothe accumulation of waste inside of easing pressing against the rollcausing it to slip and fail to draw the sliver forward. If the situationis not noticed by the operative the accumulations will soon till thecasing and back up against the combing members with the result ofcausing great damage to said members.

The object of my invention is to eliminate this objectionableconstruction by substituting positive driving means for the n'essureroll whereby the proper functions of the roll are obtained.

In describing'my invention in detail reference will be had to the.accompanying drawings wherein like symbols refer to like orcorresponding parts throughout the several views and in which:

Figure 1 is an elevation showing somewhat diagrammatically the rear sideof a combing machine having a waste collector embodying my invention.Figure 2 represents a sectional elevation on line 22- of Figure 1.Figure 3-shows the end view of the pressure roll driving means. Figure tis a sectional elevation on line H of Figure 3. Figure 5 is an enlargedsectional view on line 5-5 of Figure 3 of the pressure roll supportingmeans. Figure 6' is: a sectional view on line (36 of Figure 3;

Referring to the drawings 12 indicates a portion of a combing machine,13 indicates the rotary combing member, and 14- is the brush by whichthe waste is stripped from the combing member. These parts formindividual units or heads, a plurality of which are used in combingmachines as now constructed.

Associated with these heads is a waste collector comprising a casing 15for each head inelosing the combing and stripping members, a rotaryperforated screen 16, an air exhausting apparatus (not shown) connectedto the rotary screen 16 by pipe 17 and so arranged that the air currentsucks the waste into the casings from the strip ping brushes anddeposits it onto the screen the rotation of which i carries it under theroll 18 which compresses it into the form of a fleece or sliver and isthen removed from the machine. In machines as at present constructedeach head is provided with an indi-' vidual compressing roll infrictional contact with the surface of the rotary screen at theintersection of the casing and the screen. It often happens that a bunchof waste will be caught under the roll thus stopping the rotation of theroll and causing the waste to accumulate to such an extent as to back upinto the combing member resulting in great injury to the combing member;To eliminate this faulty construction I provide a construction'wherebythe compression roll does not depend on the uncertain frictional contactwith the rotary screen for its motion but has means whereby the rollispositively driven. Instead of having an independent frictionallydriven roll for each head I make use of a positively driven compressionroll cooperating with the screen at the intersections of'the casings andscreenof two or more heads, and is rotatable in bearings fixed ,to theframing of the machine. Preferably one end of the roll runs on a springdetent center 19 whereby the operative may easily remove the roll forcleaning purposes, the other end of the roll being supported in anordinary U shaped bearingQai fixed to a stationary part of the machine.The detentcenter is held in a bracket 20 which also serves as asupporter of the shaft 21 on whiph the rotary screen turns. Rotarymotion is imparted to the roll 18 by a gear 22 fixed on one end ofthe'roll and cooperating with gear 23 fixed to the rotary screen 16which derives its motion from chain gear 25 on lap/roll shaft 26,transmitting by chain 2? to chain gear 28 rotatable on a stud 29 fixedin bracket 20. To the hub of the 7 chain gear-28 is fixed the gear 30which transmits motion to the rotary screen by coing to generate an aircurrent therethrough whereby the waste from the stripper brush iscollected on the screen and positively driven means cooperating with thescreen for compressing the waste into a sliver.

2. In a combing machine, the combination with a combing member and astripping brush, a casing inclosing said combing member and strippingbrush, a perforated rotary screen,'an air exhausting means connected tosaid screen and operating to generate an air current therethroughwhereby the waste from the stripper brush is collected on the screen,and a positively driven roll cooperating with the screen at theintersection of the casing and the screen whereby the Waste iscompressed into a sliver. I

3. In a combing machine having a plurality of heads each con'iprising acombing member and a stripping brush, a casing inclosing the members ofeach head, a perforated rotary screen, an air exhausting means connectedto said screen and operatmg to generate an air current therethrough apositively driven compression roll coop},

crating with the screen at the intersections of the casings and thescreen, bearings supporting the roll and means to facilitate the removalof the roll from its bearings.

In testimony whereof, I have signed this specification.
